It is; flatpak application generally cannot read host settings. But I doubt that's relevant to this bug. Unless you've disabled hardware acceleration, it will be enabled. A quick way to test is to use the environment variable WEBKIT_DISABLE_COMPOSITING_MODE=1 (e.g. flatpak run --env=WEBKIT_DISABLE_COMPOSITING_MODE=1 ...)

I will imminently update the master runtime to WebKitGTK 2.41.90. Please try that and report back whether it makes any difference. There have been so many graphics-related fixes recently that it probably doesn't make sense to investigate until we know whether it still occurs with all the latest fixes.
